caveman-kiss

KISS = Keep It Simple, Stupid: the old engineering maxim that a system works best when it's kept simple rather than made complicated.

A Claude Code plugin that holds both your code and its replies to that maxim: the simplest thing that works, written once, said in the fewest words. Always on, with a [CAVEMAN-KISS] statusline badge.

It keeps four habits firing on every response:

• Simplest thing that works: does it need to exist (YAGNI)? → standard library / built-ins → native feature → installed dep → one line → minimum code.
• Written once: dedupe on the third repeat, never speculatively. A wrong abstraction costs more than duplication.
• Clean seams: one module, one reason to change. Split only when concerns genuinely tangle.
• Fewest words: code first, terse prose, no dev/prompt dump in user-facing output.

Never simplifies away validation, error handling, security, accessibility, or tests. When the habits conflict, the simplest design that stays correct and secure wins.

Install

/plugin marketplace add wmsouza/caveman-kiss
/plugin install caveman-kiss

Use

On by default. /caveman-kiss off (or "stop kiss" / "normal mode") to pause, /caveman-kiss to resume. One mode, no levels to tune.

For the [CAVEMAN-KISS] badge, point your statusline at hooks/caveman-kiss-statusline.ps1 (Windows) or hooks/caveman-kiss-statusline.sh in ~/.claude/settings.json.

Credits

Built on the ideas of two plugins it shamelessly fuses:

• ponytail by Dietrich Gebert: the lazy-senior-dev / YAGNI build philosophy.
• caveman by Julius Brussee: the terse-output mode and the plugin/hook/badge pattern this borrows.
